Abstract

A simplified rail gun model is established and three dimensional finite element method of electromagnetic (EM) field is used to analyze the model parameters. The parameters include: inductance gradient, resistance gradient, magnetic induction intensity, magnetic force etc. The simulation result indicates that the load of rail gun may be equivalent to the nonlinear resistance, inductance and back electromotive force.
